What exacly is the maximum acceptable jitter for the input reference clock ?The chip we are using is the STM32U585QIIx. We consider using an external clock from a VCO as HSE, and increase the frequency of the clock using the internal PLL. The VCO is ...
There is "96-bit unique ID" in the datasheet (DS13514 Rev 2 ). The feature is also listed on product page . But there is no mention of unique ID in the reference manual (RM0454 Rev 5). Does the MCU have unique ID and how it can be accessed?
Hi everyone,I'm working with a Nucleo-64 evaluation board equipped with an STM32L476. To make BLE I added the IDB05A1 module.I want to create a simple scanner, but browsing through the examples in ST32CubeMX, I can't find an example of a scanner usin...
Hi, We want to incorporate the STLink firmware binary provided by STMicroelectronics here onto our custom STM32 board with stlink circuit. However, we would like to seek clarification on whether this usage would allow us to sell our custom board comm...
Hi, forgive the newby question, but I'm a newby to STM and micros in general. I'm a hardware engineer and have not really ventured too far into the code world until now.I need to monitor 4 GPIOs. They could be any of 3 states: PWM (~50% duty, 1 secon...
"The ADC of STM32L151VE is not functioning properly. The output values of the ADC appear to be random. Does anyone know how to resolve this issue?
Hello,I need with STM32F4 to read datas (multiple bytes) from a sensor connected to SPI3 and transfert the bytes i read from this SPI3 to an external memory connected to SPI1.I would like to use DMA (if possible). Seemingly SPI1 can only be connected...
Hello community, I'm working on a STM32F107VCT6 where I have practically (by means of very basic filtering) shorted on the PCB VDD/VDDA/VREF+/VBAT and VSS/VSSA/VREF-. I've runned out of pins so I was wondering if there were a way to measure the pow...
I have over 25 years in embedded design but I am new to ST and ARM cores. I am looking at the STM32 MCU's to replace a 32bit MCU I am already using, the only feature I don't need is the graphics system as we have our own GUI hardware and firmware. I ...
